ARMOR FOR TIRES.

Application filed June a, 1910. Serial No. 565,719.

To all whom it may concern:

Be it known that I, JOHN M. BARNETT, citizen of the United States, residing at Oskaloosa, in the county of Mahaska and State of Iowa, have invented certain new and useful Improvements in Armor for Tires, of

v which the following is a specification.

This invention comprehends certain new and useful improvements in armor for pneuw matic tires, and the object of the invention is an improved device of this character which is arranged to effectually inclose the tread in 'order to protect the same from puncture and wear and to prevent skidding, and which at the same time has suflicient play so as notto interfere with the resiliency of the tire, the armor being adapted to be readily applied to the exterior of the tire, and embodying to a marked degree the characteristics of simplicity, durability and strength. 7

With this and other objects in view that will more fully appear as the '*-description proceeds, the invention consists in certain -construct-ions and arrangements of the parts that I shall hereinafter fully describe, and then point out the novel-features thereof in the appended claims.

Fora full understanding of the invention and the merits thereof, and to acquirea knowledge of the details of construction, reference is to be hadto the following description and accompanying drawing, 1n which:

35 Figurel is-a side elevation'of a wheel equipped with my improved armor; Fig. 2 is a transverse section of the tire and armor, thesection being taken on the line 22 of Fig. 1; Fig. 3 is a plan view of the armor 40 looking from the inside; Fig. 4 is a section of one of the disks and the plate attached thereto; Fig. 5.is a bottom plan view thereof; Fig. 6 is-an edge view; Fig. 7 is a side .view; and, Fig. 8 is a detail view of one of 5 the blocks.

Corresponding and like parts are referred to in the following description and'indicated in all the views of the drawing by the same reference characters.

For the purpose of illustration, I have shown and described my improved armor as appliedjto awheel 1 which has a pneumatic tire 2, and which may be of any desired or approvedconstruction or design. Arranged on opposite sides of the tire are two rings-3 medianly on the tread, nd withyfl between adjacent blocks.

' the threaded contour of the tread. Incorporated infhis netting, are a plurality of metallic blocksor disks 5 which are arranged i W dinal rows with the middle row of adjacentrows positioned in staggered lifelation. The blocks 5 areformed 1n.,the1r marginal portions with series of apertures The blocks 5 are also formed vwith central threaded apertures 9, and in their outer' faces around such 'ape'r" tures, with bosses 10, the latter being designed to be received in openingsin plates or scales 11 which complete the-formation of the mail-like armor. In the preferred structure, the bosses and openings of the plates are correspondingly polygonal in cross section in order to ,hold the latter against anyturning movement relative to the former. v

"'12 designates a plurality of screws or threaded studs that are inserted through the openings in the plates and engaged with openings 9- in order to detachably secure the scales to the respective disks, sundry of .said studs being provided with enlarged heads 13 which are adapted to prevent the tire from slipping or skidding,

. and which are preferably polygonal in cross section so as to be susceptiblelofbeing.ma nipulated by a wrench or similartool. The remaining studs have heads of theconventional screw form.

The plates or scales may be of-anysuitable size or shape, and overlap eachv other so that the armor completely incloses the Specification of Letters Patent. Patented J 11118 1 3, 19.11.

I between which is secured a that el rtends across andjconformswiththe 6 to which short chains 7 are connectedifat.; one end, the opposite ends of the chains being attached to rings 8 that are interposed tread to protect the same from wear and puncture. It will be observed, by reference to Fig. 1, that the forward portion ofeach scale of a longitudinal row overlaps the rear portion ofthe scale just in front, such anarrangement being advantageous, in that the possibility of tacks or like objects working between the plates during the rotation of the wheel, is effectually precluded.

The separate armor plates are independently supported by their bosses in spaced relation to the chain fabric,-and hence are afforded a maximum amount of play so as not to interfere with 1 the natural resiliency 14 through of the tire. A plurality of short chains 7 p are connected to each of the blocks 5 and permit the same to have a limited turning or twisting movement without injury to the 5 chain fabric, thereby attaining a material advantage over the ordinary form of armor wherein the plates are riveted to a canvas or like fabric base or foundation. The armor isapplied to the Wheel when the tire is deflated. Upon the inflation of. the tire the .armor conforms to the contour of the tread and .te'ndsto remain thereon against accidental displacement; As a precautionary measure, however, the rings '3 are equipped at corresponding points with loops whichare inserted straps 15 that are buckled across the telly of the wheel.

Anarmor constructed in accordance with my invention, may be manufactured at a excessive Wear, and is susceptible of being easily and cheaply repaired, and without the necessity of employing skilled labor, thus recommending itself particularly for use by automobilists and others using vehicles having pneumatic tires.
